Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed. June 23, 1904. Serial No. 213,877.

To all whom, it may concern:

Be it known that l, CHARLES VICTOR SHAN- NON, clerk, of the city of Dawson, in the Yukon Territory, Canada, have invented new and useful Improvements in Copy-Holders; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to copy-holders, and has for its objects the rovision of a device of this general class whic will be especially useful for holding manuscript-copy for transcribing to a type-Writing machine and is also adapted for other uses of a like character.

The device embodies a compact and easilymani ulated mechanism for holding down the sleets or leaves of the copy, also a spacer mechanism for dropping down to the next line while copying, and an indicator for showing the movement of thespacing mechanism.

The invention consists particularly in a movable rack-bar and carriage and a stationary rack bar located adjacent the movable bar, andby the manipulation of the movable bar the carriage is moved from its predetermined position to a position where the linebar, which is carried by the carriage, will rest under the next line ofcopy below, or, in other words, the line-bar is dropped from line to line as the copying proceeds down the page.

The invention further consists in certain novel features of construction and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of the device as a whole in position ready for use. Fig. 2 is a view of the device, enlarged7 with the top or cover removed, showing the device complete. Fig. 3 is a broken detail view from the inside of the device, showing the two rackbars and carriage and connecting-pawls. Fig. 4 is a view similar to Fig. 3 as seen from the reverse side, and Fig. 5 is a detail view of part of the movable rack-bar.

The box or casing 1 has located therein running lengthwise thereof two arallel rackbars, as the movable bar 2 anc the stationary bar 3, said bars being held or guided, as the case may be, in the guide-blocks 4 and 5. A spring-rod, as 6, is secured to the bottom of the casing 1 and has its end protruding through a slot 7 in the end of the box, the end being provided with a handle 8, by which the spring-bar may be depressed in the slot 7. A rock-bar 9, located in bearing-lugs 10 10, has

a crank end 11, turned in and located under the spring-depressin rod 6, and said bar 1s also provlded with lifting-bars 12 12, which have their free ends located in slots 13 in the movable rack-bar 2. A spring 14 bears down upon each of the said lifting-bars 12. From this construction it will be understood that by depressing lever or spring-rod 6 rock-bar 9 is turned and movable rack-bar 2 is 'lifted by the lifting-bars 12, the springs 14 acting to retard the movement ofthe bars and to return them to position when pressure on handle 8 is released.

The space-bar 15 is carried by the carriage 16. Said carriage is provided with wheels and travels on the track 17. A handle 19 on the carriage projects through slot 20 of the casing 1. The space-bar 15 is hinged to the carriage by the connection at slot 22 and pivot 23, the pivot passing through a portion of the depressing -handle 24 and carriagehandle 19 and rod 26 (an extension of the space-bar 15) being held in slot 22 by locking-nuts 26 Thus by pressure on handle 24 the space-bar 15 may be lifted from the sheet of copy. The carriage may be lifted or sllioved up on the tracks by means of the hand e 19.

Carriage 16 is adapted to travel alongside and parallel with the two rack-bars 2 and 3 and is provided with a series of three pawls 27, which are pivoted on the inside of the carriage and extend over both rack-bars. The pawls 27 normally rest on the teeth ofthe stationary rack-bar 3 and hold the carriage stationary when the device is raised to position shown in Fig. 1.r Thus when it is desirable or necessary to lower the space-bar 15 a line by depressing the handle 8 the movable bar 2 is lifted, as has been described. The teeth of the bar engage the pawls 27 lifting them from the stationary rack-bar teeth, and when the pawls have been lifted the carriage is free to descend, riding on its wheels. The movable bar 2 is also free to slide downwardly within limits, and both bar and carriage move downwardly. By relieving pressure on the handle 8 movable bar 2 is allowed to fall or be positively returned to lowered position by the springs 14 acting on lifting-bars 12. When the supporting rack-bar is withdrawn from the pawls 27, said pawls fall on the teeth of stationary bar 3 and the carriage is stopped in its movement, as is ofcourse the space-bar 15, carried thereby. The movable bar is permitted to move only Within the IOO IIO

limits of the slots 13 but said slots may be as long as is desirable and such'movement varied. The movable -bar is returned to its ori lnal normal position by the spring 28, as wil be understood.

The distance of the drop of the movable bar '2 may? be regulated by the thumb-screw H, Working in block G. By turning the screw the indicator-arm W, located in the path of movementof the bar 2, will obstruct and stop the movement of said bar. The end vofthe indicatorarm is turned up and projects through the slot W in the cover of the holder and slides along a graduated scale, as indicated,`when the nut or thumb screw H is turned, thus indicating the ,distance the `marker 15 will descend when pressureis appliedto the spacer 8.

, The book-holder 30,-located at the top of the box or casing has a rod or bar 31, over which the note-booky may. be hung and there held. By turning the crankfarm 32-down Jfrom position i-n Fig.2 to position of bar 31 inFig. 1 thelcopybook maybe located in pro-perposition for work withthe space or line-bar 15 Ldisposeid: across the face of jthe copy-sheets.

Having thus'fully described my invention, what I claim, and desire to secure by Letters atent, is-

`1.,In a copy-holder, the stationary rackbar and carriage connectedthereto, a movable rack-bar havin@F slots therein,a rock-bar having lftingfbarsliocated in said. slots, and a 'depressible spring-rod for rocking said rock-bar to lift the movable bai", whereby the carriage is disengaged from the stationary Iack-bar and engaged by the movable rack- 2. In a copy-holder and spacer, a stationary rack-bar and carriage connected thereto, a' space-bar on said carriage, a movable rackbar having slots therein, a rock-bar having lifting-rods located in said slots, a depressible rod bearin on said rock-bar adapted to lift the movab e bar whereby the carriage is disengaged vfrom the stationary rack-bar and engaged by the movable rack-bar, and means for returning the movable rack-bar to normal position when pressure is released on the depressible bar, all combined substantially as described.

3. The combination of a stationary rackbar and a slotted movable rack-bar, a carriage and a series of paWls carried thereby engaging said stationary bar, a space-bar carried by the carriage, a rock-bar having rockerarms in the slots of the movable bar, for lifting said bar whereby the pawls are disengaged from the stationary bar and engaged by the movable bar, and a spring connected to the movable bar for returning it to original position.

.In testimony whereof I have signed. my name to this specification in the presence of two subscribing witnesses.
